Ein gattungsgemäßes Fahrzeugdach ist aus der DE 103 28 092 A1 bekannt. Bei diesem ist eine große Dachplatte, die gleichzeitig die Seitenholme umfasst, im Bereich der Seitenholme mit einer nicht transparenten Klebefolie versehen oder durch eine Bedruckung an der Innenseite der Dachplatte nicht transparent ausgebildet.A generic vehicle roof is from the DE 103 28 092 A1 known. In this, a large roof panel, which also includes the side rails, provided in the region of the side rails with a non-transparent adhesive film or formed by a print on the inside of the roof panel is not transparent.

Aus der DE 101 31 884 A1 ist ein Kunststoffdeckel eines Fahrzeugdachs bekannt, bei dem der Randbereich auf der Innenseite von einem nicht transparenten Kunststoffmaterial bedeckt ist, das gleichzeitig eine Versteifung bildet.From the DE 101 31 884 A1 a plastic cover of a vehicle roof is known in which the edge region is covered on the inside by a non-transparent plastic material, which forms a stiffener at the same time.

Aus der DE 101 15 568 B4 ist ein zweischaliges Dachelement eines Fahrzeugs bekannt, bei dem die Außenseite von einer mehrschichtigen Folie gebildet wird, die ganz außen liegend eine Deckschicht aus PMMA, daran nach innen anschließend eine Farbschicht und daran anschließend eine Folienträgerschicht aus ASA/PC aufweist, die für die Verbindung zu einem hinterspritzten Verstärkungsmaterial bildet. Die Folienträgerschicht kann auch eingefärbt sein, so dass eine separate Farbschicht dann entfällt.From the DE 101 15 568 B4 a double-shell roof element of a vehicle is known, in which the outside is formed by a multilayer film, the outermost lying a cover layer of PMMA, then inside a color layer and then a film backing layer of ASA / PC, which for the connection to forms a back-injected reinforcing material. The film carrier layer can also be colored, so that a separate color layer is then omitted.

Der Erfindung liegt die Aufgabe zugrunde, ein Fahrzeugdach zu schaffen, bei dem ein aus Kunststoff bestehendes Dachteil sich besser in das Gesamtbild des Fahrzeugs einfügt.The invention has for its object to provide a vehicle roof, in which a plastic existing roof part fits better into the overall picture of the vehicle.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved by the features of claim 1. Advantageous embodiments of the invention are specified in the subclaims.

Die Erfindung sieht im Kern vor, dass in das Dachteil aus Polycarbonat zumindest partiell jedoch bevorzugt vollflächig eine Folie integriert ist, die die Farbe des Fahrzeugs aufweist.The invention provides in essence that in the roof part made of polycarbonate at least partially but preferably over the entire surface of a film is integrated, which has the color of the vehicle.

Gemäß einer besonders vorteilhaften ersten Ausführungsform ist die Folie als außen liegende Folie vorgesehen, an die sich bevorzugt nach außen nur noch eine dünne transparente Schicht aus einem Kratzschutzlack anschließt.According to a particularly advantageous first embodiment, the film is provided as an outer film, to which preferably only a thin transparent layer of a scratch-resistant coating adjoins the outside.

Gemäß einer vorteilhaften zweiten Ausführungsform ist vorgesehen, dass die Folie zwischen zwei das Dachteil bildende Schichten aus Kunststoff eingebettet ist. Dadurch stellt sich bei einer transparenten oberen Kunststoffschicht eine interessante optische Tiefenwirkung der Farbe des Dachteils ein.According to an advantageous second embodiment, it is provided that the film between two the roof part forming layers of plastic is embedded. As a result, an interesting visual depth effect of the color of the roof part arises in the case of a transparent upper plastic layer.

Gemäß einer dritten Variante kann die Folie auch auf der Unterseite eines aus einer oder mehreren Schichten bestehenden Kunststoff-Dachteils angeordnet sein. In diesem Fall wird die optische Tiefenwirkung der Farbe noch verstärkt.According to a third variant, the film may also be arranged on the underside of a plastic roof part consisting of one or more layers. In this case, the optical depth effect of the color is enhanced.

Die Folie ist bevorzugt mit einem aus Polycarbonat (PC) bestehenden Dachteil verbunden. Bevorzugt wird sie mit dem Polycarbonat (PC) hinterspritzt. Die Folie selbst besteht aus einem Polycarbonat (PC), einem Polycarbonat-Blend, wie Acrylnitril-Butadien-Styrol-Polycarbonat-Blend (ABS-PC), einem PC-Copolymer oder einem anderen PC-kompatiblen Material, wie Polyethylenterephthalat (PET) oder Polymethylmethacrylat (PMMA).The film is preferably connected to a polycarbonate (PC) existing roof part. Preferably, it is back-injected with the polycarbonate (PC). The film itself consists of a polycarbonate (PC), a polycarbonate blend, such as acrylonitrile-butadiene-styrene-polycarbonate blend (ABS-PC), a PC copolymer or another PC-compatible material, such as polyethylene terephthalate (PET) or Polymethyl methacrylate (PMMA).

Die Folie ist bevorzugt komplett in der Fahrzeugfarbe eingefärbt; sie kann jedoch auch an ihrer Oberseite oder Unterseite in Fahrzeugfarbe lackiert oder bedruckt sein. Es können optional Flächenanteile vorgesehen sein, bei denen die Farbschicht so dünn ist, dass eine Teiltransparenz entsteht, die zum Fahrzeuginnenraum hin einen Lichtdurchtritt ermöglicht. Die Übergänge von einem opaken zu einem transparenten oder teiltransparenten Flächenbereich des Dachteils können fließend wie Farbverläufe gestaltet werden.The film is preferably completely colored in the vehicle color; However, it can also be painted or printed on its top or bottom in vehicle color. It can optionally be provided surface portions in which the color layer is so thin that a partial transparency is formed, which allows the vehicle interior to a passage of light. The transitions from an opaque to a transparent or semi-transparent surface area of the roof part can be designed as fluent as color gradients.

a schematic partial cross section of a third embodiment of the vehicle roof with a film arranged below a plastic layer.

Das in Fig. 1 gezeigte Fahrzeugdach 10 setzt sich zusammen aus einem vorderen Dachteil 12, einem hinteren Dachteil 14, einem vorderen Querholm 16, einem hinteren Querholm 18 und zu beiden Seiten angeordneten Seitenholmen 20. Die Seitenholme 20 können als separate Bauteile mit der A-Säule 24, der B-Säule 26 und der C- beziehungsweise D-Säule 28 verbunden sein, an denen die Dachteile 12 bzw. 14 fest oder bewegbar gelagert sind. Es ist jedoch ebenso möglich, tragende Holmstrukturen 22 unmittelbar an den seitlichen Bereichen der Dachteile 12 bzw. 14 mit anzuformen. Die Dachteile 12 bzw. 14 sind bevorzugt Bestandteile eines RHT (Retractable Hardtop), also eines Festelement-Cabriolets, bei dem die in sich steifen Dachteile zur Freigabe einer Cabrio-artigen Dachöffnung mittels einer Mechnik in einen Stauraum im hinteren Bereich des Fahrzeugs bewegt werden können.The vehicle roof 10 shown in FIG. 1 is composed of a front roof part 12, a rear roof part 14, a front cross member 16, a rear cross member 18 and side members 20 arranged on both sides. The side members 20 may be provided as separate components with the A side member. Pillar 24, the B-pillar 26 and the C or D-pillar 28 may be connected to which the roof parts 12 and 14 are mounted fixed or movable. However, it is also possible to form supporting spar structures 22 directly on the lateral regions of the roof parts 12 and 14, respectively. The roof parts 12 and 14 are preferably components of a RHT (Retractable Hardtop), ie a fixed-element convertible, in which the inherently rigid roof parts to release a convertible-like roof opening can be moved by means of a Mechnik in a storage space in the rear of the vehicle ,

Die Fign. 2 bis 4 zeigen drei unterschiedliche Ausführungsformen eines erfindungsgemäßen Dachteils. Exemplarisch ist dort das Dachteil 12 in einem Teilquerschnitt zur Verdeutlichung des Schichtenaufbaus dargestellt. Das Dachteil 14 und die Holme 16, 18, 20 können in gleicher Weise aufgebaut sein.The Fign. FIGS. 2 to 4 show three different embodiments of a roof part according to the invention. As an example, the roof part 12 is shown there in a partial cross-section to illustrate the layer structure. The roof part 14 and the spars 16, 18, 20 may be constructed in the same way.

Allen drei Ausführungsbeispielen gemeinsam ist, dass die Dachteile 12 bzw. 14, vorzugsweise mit den Holmen 16, 18, 20, mittels einer in der Fahrzeugfarbe, beziehungsweise der Farbe des Fahrzeugdachs eingefärbten Folie 30 an die Farbe des Fahrzeugs bzw. des Fahrzeugdachs angepaßt sind. Die Dachteile 12 bzw. 14 können daher beim Fahrzeugzulieferer für den Einbau am Band beim Fahrzeughersteller fertig vorbereitet werden. Die Dachteile 12 bzw. 14 fügen sich dadurch harmonisch in das Gesamtbild des Fahrzeugs ein. Ein nachträgliches lackieren beim Fahrzeughersteller ist nicht mehr erforderlich.All three embodiments have in common is that the roof parts 12 and 14, preferably with the bars 16, 18, 20, by means of a colored in the vehicle color, or the color of the vehicle roof film 30 are adapted to the color of the vehicle or the vehicle roof. The roof parts 12 and 14 can therefore be prepared ready for installation on the belt at the vehicle manufacturer at the vehicle supplier. The roof parts 12 and 14 fit harmoniously into the overall picture of the vehicle. Subsequent painting at the vehicle manufacturer is no longer necessary.

Bei der Ausführungsform gemäß Figur 2 ist die Folie 30 an der Oberseite des Dachteils 12 angeordnet. Darüber ist lediglich noch eine dünne kratzfeste Lackschicht 36 aus einem transparenten Lack angeordnet. Die Folie 30 ist mit einer ersten Kunststoffschicht 32 aus Polycarbonat hinterspritzt. Zur zusätzlichen Versteifung ist optional eine weitere Kunststoffschicht 34, bevorzugt ebenfalls aus Polycarbonat, an der Unterseite des Dachteils 12 angeordnet.In the embodiment according to FIG. 2, the film 30 is arranged on the upper side of the roof part 12. In addition, only a thin scratch-resistant paint layer 36 is arranged from a transparent lacquer. The film 30 is back-injected with a first plastic layer 32 made of polycarbonate. For additional stiffening, a further plastic layer 34, preferably also made of polycarbonate, is optionally arranged on the underside of the roof part 12.

Die Folie 30 besteht aus einem Polycarbonat, (PC), einem Polycarbonat-Blend, wie Acrylnitril-Butadien-Styrol-Palycarbonat-Blend (ABS-PC), einem PC-Copolymer oder einem anderen PC-kompatiblen Material, wie Polyethylenterephthalat (PET) oder Polymethylmethacrylat (PMMA). Sie ist entweder komplett in Fahrzeugfarbe durchgefärbt oder - vor dem Hinterspritzen oder dem Aufbringen der kratzfesten Lackschicht - an einer ihrer Seiten, bevorzugt an ihrer Oberseite mit einer Lackschicht in Fahrzeugfarbe lackiert oder durch Bedruckung in Fahrzeugfarbe bedruckt. Dies gilt auch für die folgenden Ausführungsbeispiele gemäß den Fign. 3 und 4.The film 30 consists of a polycarbonate, (PC), a polycarbonate blend, such as acrylonitrile-butadiene-styrene-palycarbonate blend (ABS-PC), a PC copolymer or another PC-compatible material, such as polyethylene terephthalate (PET). or polymethyl methacrylate (PMMA). It is either completely colored in vehicle color or - before spraying or applying the scratch-resistant paint layer - on one side, preferably painted on its upper side with a paint layer in vehicle color or printed by printing in vehicle color. This also applies to the following embodiments according to FIGS. 3 and 4.

Bei der Ausführungsform gemäß Figur 3 ist die Folie 30 zwischen zwei Kunststoffschichten 38 beziehungsweise 40 eingebettet. Zumindest die obere Kunststoffschicht 38 ist transparent ausgebildet. Bevorzugt sind beide Kunststoffschichten 38 bzw. 40 aus Polycarbonat hergestellt und durch Spritzen auf die Folie 30 aufgebracht. Optional ist auf der Außenseite der äußeren Kunststoffschicht 38 noch eine kratzfeste Lackschicht 36, wie im ersten Ausführungsbeispiel gemäß Figur 2 vorgesehen. Durch die Anordnung der Folie 30 unterhalb der Kunststoffschicht 38 wird die Einfärbung der Folie 30 durch das darüber liegende transparente Material der Kunststoffschicht 38 mit einer gewissen Tiefenwirkung wahrgenommen. Hierdurch kann ein besonderer gewünschter optische Effekt bei der Gestaltung des Fahrzeugdachs erzielt werden.In the embodiment according to FIG. 3, the film 30 is embedded between two plastic layers 38 and 40, respectively. At least the upper plastic layer 38 is transparent. Preferably, both plastic layers 38 and 40 are made of polycarbonate and applied to the film 30 by spraying. Optionally, on the outside of the outer plastic layer 38 is still a scratch-resistant lacquer layer 36, as provided in the first embodiment shown in FIG. By the arrangement of the film 30 below the plastic layer 38, the coloring of the film 30 is perceived by the overlying transparent material of the plastic layer 38 with a certain depth effect. In this way, a particular desired optical effect in the design of the vehicle roof can be achieved.

Das gleiche gilt für das Ausführungsbeispiel gemäß Figur 4, bei dem die Folie 30 unterhalb mindestens einer oberen transparenten Kunststoffschicht 38 angeordnet ist. Auch für dieses Ausführungsbeispiel gilt, dass oberhalb der Kunststoffschicht 38 optional wieder eine kratzfeste Lackschicht 36 angeordnet sein kann. Ferner können auch mehrere transparente Kunststoffschichten über der Folie 30 angeordnet sein. Bevorzugt bestehen auch hier alle Kunststoffschichten 38 aus Polycarbonat.The same applies to the embodiment according to FIG. 4, in which the film 30 is arranged below at least one upper transparent plastic layer 38. For this exemplary embodiment, too, a scratch-resistant lacquer layer 36 can optionally be arranged above the plastic layer 38 again. Furthermore, a plurality of transparent plastic layers may be arranged above the film 30. Here, too, all plastic layers 38 preferably consist of polycarbonate.

Durch die Erfindung wird eine einfache kostengünstige Möglichkeit geschaffen, ein Fahrzeugdachteil oder ein gesamtes Dachmodul aus Kunststoff gegebenenfalls mit daran integrierten Holmen an das optische Erscheinungsbild eines Fahrzeugs anzupassen. Die Oberfläche ist dabei hoch glänzend (glazing), wodurch die Farbe der Folie sehr gut zur Geltung kommt. Durch die Integration der Farbe in die Folie ist diese hervorragend vor Abnutzung, Verwitterung oder mechanischer Beschädigung durch Kratzer oder Hagelschlag geschützt. Auch wenn vorstehend von Fahrzeugdachteilen gesprochen wird, ist für den Fachmann klar, dass sich die Erfindung auch für andere außenliegende Karosserieteile, wie Türen, Motorhaube oder Heckklappe von Fahrzeugen hervorragend eignet.The invention provides a simple cost-effective way to adapt a vehicle roof part or an entire roof module made of plastic, where appropriate, integrated with Holmen to the visual appearance of a vehicle. The surface is glossy (glazing), whereby the color of the film is very good effect. By integrating the paint into the film, it is superbly protected against wear, weathering or mechanical damage caused by scratches or hailstorms. Even though it is referred to above as vehicle roof parts, it is clear to the person skilled in the art that the invention is also outstandingly suitable for other exterior body parts, such as doors, bonnet or tailgate of vehicles.
